Food quality assurance (FQA) is a central element in ensuring that food products remain safe, consistent, and trusted by consumers. Instead of focusing solely on final inspections, it integrates technical processes, managerial accountability, and cultural practices into one coherent framework. This chapter outlines the main principles of FQA, from its origins in traditional inspection toward the modern preventive and systems-based models, while emphasizing its increasing role in global food governance. Core attention is given to the established methods of good manufacturing practices (GMPs), good hygiene practices (GHPs), and hazard analysis and critical control points (HACCP), which remain fundamental for risk management and consumer protection. In addition, the chapter explores four essential pillars of contemporary assurance-food safety, quality management, regulatory compliance, and sustainability-illustrating how these dimensions collectively reinforce trust and resilience in food systems.

Risk assessment is the process used to identify hazards and analyze what could happen if the hazards do occur. Risk assessment is also used to ensure the production of safe food and ensures the control is based on a scientific approach to solve its problems. Risk assessment includes procedures including (i) hazard identification, (ii) hazard characterization, (iii) exposure assessment, and (iv) risk characterization. The main groups of people who use risk assessment are the industry and the regulatory officials. There are different types of hazards, including chemical hazards, biological hazards, and physical hazards. Hazards are any foreign objects that are not found in the food and might be present; they are usually hard, liquid, visible, invisible to the eye, or sharp objects of varying sizes that can cause harm in the mouth, throat, or intestine. They can include materials like glass, metal, plastic, stone, wood, pesticides, aflatoxins, bacteria, viruses, and insects. They could also be introduced to food usually through chemicals used for cleaning within the facility, and ingredients stored in the facility, as well as chemicals that contaminate the water supply and metals from equipment, utensils, and containers.

Besides health, the global rise of food contamination poses a profound threat to the economy, particularly in low- and middle-income countries. Despite established regulatory frameworks such as hazard analysis and critical control points (HACCP), Food Safety Modernization Act (FSMA), and International Organization for Standardization (ISO) 22000, it still remains challenging to control foodborne outbreaks and requires a sustainable approach. Herein, this chapter provides timely insights about the role of engineering controls, which can further be divided into primary controls (e.g., air handling, filtration, and zoning) and secondary controls (e.g., antimicrobial surfaces, hygienic design, and personnel flow management). In recent years, although advances in Internet of Things (IoT)-based sensors, robotics, and smart antimicrobial materials have facilitated rapid progress, limited standardization, validation, and scalability necessitate urgent, multisectoral action. In addition, this chapter identifies other context-specific challenges associated with small and medium-sized sectors, including poor infrastructure, insufficient administrative measures, and financial constraints.

Automated quality control (QC) is changing how the industry ensures product safety, product uniformity, and compliance in the fast-paced world of food engineering. Historically, food production QC has relied on extensive manual inspection, batch testing, and operator skills. Traditional approaches have previously sufficed, but smarter real-time data-driven systems are steadily taking over as food supply becomes increasingly complex and consumer demands more stringent. Contrived innovations, such as the inclusion of machine vision systems, robotics, Internet of Things (IoT) devices, cloud monitoring systems, and artificial intelligence (AI)-based decision tools, have driven the change in QC to automation. Today, these technologies are used in industries across several sectors to allow accurate, scalable, and continuous inspection capabilities that can even surpass those performed by humans. In food engineering, automation is essential for monitoring microbiological safety, governance of packaging defects, control of the emphasis of thermal and physical parameters of food processing, and reporting at each step of the supply chain. It can help food processors in the dairy, meat, and beverage industries, as well as in bread manufacturing and packaged food production, to produce more safely and efficiently by enabling them to achieve increased throughput and regulatory compliance, lessen dependence on labor, and improve product quality. Testing applications include hyperspectral imaging, thermographic inspection, AI-driven anomaly detection, and real-time process analytics. However, beyond technology, the convergence of automated QC touches on regulations and compliance, overwhelmingly demanding that manufacturers comply with food safety regulations, such as ISO 22000, hazard analysis and critical control points (HACCP), and the Food Safety Modernization Act (FSMA). Driven by the rising popularity of Quality 4.0, automated systems have become interlaced with more extensive Industry 4.0 architectures, where the widespread adoption of Quality 4.0 principles has facilitated and allowed predictive, adaptive, and autonomous quality management processes to be adapted to modern food production techniques.

Food safety remains a major challenge in the global food system, where biological hazards such as pathogenic bacteria, toxins, and spoilage organisms can cause severe public health crises and economic losses. Thermal engineering serves as a fundamental pillar in protecting the food supply by designing heat-based processes that make foods safe, stable, and appropriate for long-distance distribution. Traditional operations—including pasteurization, sterilization, canning, blanching, and cooking—are widely relied upon to inactivate microorganisms and enzymes using specific time–temperature combinations. The effectiveness of these treatments is evaluated using parameters such as D-value, Z-value, and F-value, which define the thermal resistance of target microorganisms and guide processors in meeting safety specifications such as commercial sterility. Innovations in thermal science continue to enhance process efficiency and precision. Emerging technologies like ohmic heating, microwave and radio-frequency heating, and pressure-assisted thermal methods facilitate more uniform heat penetration, shorten processing times, and lower energy use while better preserving the nutritional and sensory quality of food. Advanced computational tools allow engineers to simulate heat transfer patterns and identify cold spots within varying geometries, ensuring that even the most thermally protected microorganisms are inactivated during large-scale production. Such predictive approaches are essential in industrial settings where uneven heat distribution can compromise product safety. In addition to pathogen control, thermal engineering plays a significant role in preserving food quality by inactivating enzymes that otherwise cause undesirable changes in colour, flavour, and texture during storage. Thus, even milder treatments such as blanching, though not directly aimed at microbial destruction, enhance overall product acceptability and shelf life. By integrating microbial inactivation kinetics with engineering design, thermal engineering provides a robust scientific foundation to produce safe, high-quality foods. As international trade expands and consumer expectations evolve, ongoing innovation in thermal processes is indispensable for meeting global food safety demands without compromising product integrity.
